DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] The present invention or discovery relates to a new and distinctvariety of red raspberry.

[0011] Canes: Particular features of the present invention are the youngcanes can grow up to 2.0 meters in height.

[0012] Fruit: The fruit color is medium red, downey in appearance anddull. The plant produces medium to large raspberries that range from1.5-3.5 grams where the average size is about 3.0 g. The fruit lengthfor/width ratio is substantially conical with a regular outline.Further, there a small percentage of fruit have split receptacles. Theproduction of fruit occurs in late summer or early autumn.

[0013] Leaves and Foliage Characteristics: Autumn Byrd plants showbronzing of young leaves. Their petioles are purple at the base;leaflets are nearly sessile on the petiole (petiolule nearly absent).The spines are clear, with red pigmentation at the tip only. They are ofmedium density and very short. Stipules are slender, upright and short.Stems are green, with reddening near bases. The wax bloom is moderate.

[0014] Flowers: Flowers are white, self-fertile and have 5 to 6 petalsper flower. Each flower produces ample pollen for good pollination.Flowers and fruit are well exposed for easy access to picking.

[0015] Disease Resistance: The present species has exhibited resistanceto biotypes 1-4 of the large raspberry aphid, Agedophoten idaei. Thebreed is susceptible to Phytophthora root rot in glasshouse tests. Itwas slow to become infected with raspberry Leslie dwarf virus where itdid not show distinct RBSV yellow symptoms.

[0016] While the invention is susceptible of various modifications andalternative forms, specific embodiments thereof have been shown by wayof example in the drawings and will herein be described in detail. It sshould be understood, however, that it is not intended to limit theinvention to the particular forms disclosed, but, on the contrary, theintention is to cover all modifications, equivalents and alternativesfalling within the spirit and scope of the invention as expressed in theappended claims.

I claim:
 1. A new and distinct variety of red raspberry which can withstand and thrive in both Maritime Northwest and coastal California climates and which is unusually hardy and vigorous, disease resistant and a heavy producer of large crops of firm, large, sweet, juicy raspberries of deep red color and good flavor, substantially as herein shown and described and identified by characteristics described above.
